Climate change and reliable, clean, low emission fuels are the important factors for ship operators since January 1, 2020. Twelve months into the IMO2020 transition and the climate change debate is increasing as the primary discussion point on the world agenda – from industry events to the board rooms of the global corporations. Relative to this is the reliable supply of fuel since changing marine fuel represents a large investment that requires major changes to a typical ship that has a lifetime of approximately 30 years.

Wärtsilä will supply its Fixed Pitch Propeller (FPP) and EnergoProFin solutions for two container vessels owned by Yang Ming Lines, the Taiwan-based shipping company, to help the container ship operator maximize efficiency in slow steaming mode.The Wärtsilä solution is designed to enable this adjustment, allowing the speed of the two vessels to be reduced from 24 to 18 knots.The two vessels, the ‘YM Mobility’ and the ‘YM Milestone’, are the last in a series of four Yang Ming ships to be retrofitted with the Wärtsilä FPP and EnergoProFin solutions.

Marine technology specialists Wartsila’s  energy-saving propeller cap has been included in the 2019 Vancouver Fraser Port Authority’s EcoAction Program which offers harbor dues discounts for vessels calling at the Port of Vancouver that meet environmental best practices.The listing is in the vessel quieting category, which awards a 23 percent discount in harbor dues for vessels utilizing this technology. The incentive is given because the reduced cavitation offered by vessel quieting technologies reduces underwater noise.The aim is to encourage shipping companies to lessen their noise levels, since underwater noise affects the at-risk whale population in the Vancouver area of Canada.EnergoProFin incorporates fins that rotate together with the propeller.

New giant offshore wind turbines need specialized equipment to connect to the electricity grid to minimize power losses. As offshore wind farms move towards deploying higher capacity turbines of 5MW and above, energy losses during energy transfer will escalate unless higher voltages are used for power evacuation. This is leading to increasing applications of high voltage equipment in the wind energy market. ABB's intensive R&D efforts have yielded the appropriate solution by fulfilling this demand with the new and compact HV multi-functional module PASS M00 which can be inserted and fitted in narrow spaces such as a wind tower or nacelle. the cable ending. The disconnecting switch and the earthing switch are now enclosed in a single subassembly.

University of New Orleans (UNO) researcher Al Daech is afraid of heights; not a good phobia to have when your research involves space shuttles, fuel tanks, and other, big, space-age equipment. He's been trying to conquer his fears since 1981. That's when his work on corrosion fighting collided with his fear of heights. As a Martin Marietta (now called Lockheed Martin) consultant, Daech found himself on a narrow bit of scaffolding 450 ft. in the air, inspecting one of the external fuel tanks on STS-I Columbia, the first space shuttle. Three days before the launch, a pool table-size blister formed in the external tank of the STS-I. Daech's inspection showed an oily rag wiped across the tank caused the blister. He and a crew immediately went to work.
